Abstract: A computer-implemented method is for evaluating a CT data set of a coronary region of a patient regarding perivascular tissue of at least one target blood vessel. In an embodiment, the computer-implemented method automatically determines a centerline of at least the at least one target blood vessel in the CT data set; defines a region of interest as including at least one defined outer region radius around an extension interval of the centerline, the outer region radius being relatively larger than a radius of the at least one target blood vessel; and calculates at least one quantitative value from CT data in the region of interest.

Abstract: A method and a system are for calculating an output from a tomographic scrollable image stack, including a large number of generated sectional images of a tissue to be examined. In this context, a tomographic scrollable image stack is received. An output for a display is calculated. The output includes a primary image that is intended for representing the received image stack, and the output includes a secondary image with additional information. The secondary image is displayed overlaid on the primary image once an unhide signal or hide signal is received. In this context, a reference may be provided between the additional information of the secondary image and the slice of tissue for examination that is shown in the sectional image of the image stack.
